Step-by-step explanation:
Answer:
C = 8 pi cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
16 pi = pi r^2
Divide each side by pi
16 = r^2
Taking the square root
4 = r
The circumference is
C = 2 * pi *r
C = 2* pi *(4)
C = 8 pi cm
Answer:
B
Step-by-step explanation:
x is alternate exterior angles and y is 180 - x
Answer:
x _> 9 I dont have the symbol on my phone so I just put the greater than sign there
Step-by-step explanation:
1. Subtract 3 from both sides
5x > 48 - 3
2. simplofy 48 - 3 to 45
5x > 45
3. Divide both sides by 5
x > 45/5
4. Then simplify 45/5 to 9 which gives us the answer
And again I dont have the sign thats why I used the greater than sign
This one is prime. The sum of two squares doesn't factor.
The more interesting case is q^2-1, which factors into (q-1)(q+1).
